I did my own for 20 years, but when I started contracting, that stopped!

Working in different States, and having 1099 employees (back then) made it impossible for me to do them in a proficient manner.

I use a CPA that also has pro-sports clients, so she is the pro at multi State income, work related temp residencies, various State income tax rates and applications etc. and the associated expense deductibles.

returns are but a distant memory.
